Tarun travels a distance of 24km at 6 km/hr another distance of 24km at 8km/hr and a third distance of 24km at 12km/hr. His average speed for whole journey (in km/hr) is....?
Sorry 8 km per hr
2.76 is average speed
Average speed=72/9=8km/h ans
Avg speed shudnt be calculated by just taking the averages of the speeds in which case u get a wrong answer 8.6
Avg speed=total distance/total time
